Unsure how to feel...

So my fiancé texted me earlier today and started off the conversation great. We have a 14 month old son together and are getting married in November.

For his side job he works as a bartender, of course as his job he needs to be charismatic to get better to tip him more, I have no problem with him doing that. I also understand that a lot of women are bartenders too so obviously there’s gonna be tons of interaction.

I stay home with our son and usually am there by myself so Facebook and the phone is my best friend. So back to the beginning he texts me that this female coworker of his wanted advice on bedtime for her little one. I’m like GREAT! I love to help new mom’s out, I told him to give her my number and I could help her out.

Here’s where it gets weird: after I tell him this he starts acting weird like he doesn’t want to give me her number, tells me I can just send it to him and he’ll show her and tries to make me feel weird that I even want to talk to her even though this girl is coming to our wedding. I DONT EVEN KNOW HER! I just feel weird about this, very uneasy and unsure how to approach it.
